This kit is specifically engineered for Weil-McLain GV series hydronic boilers

While typically used in vertical shaft down applications with extended studs

the 511-330-088 and 1013-200 are technically identical and interchangeable

Replacing a faulty CNT0915 restores system efficiency and prevents unnecessary mechanical stress on the compressor during freezing ambient conditions

ensuring a reliable fail-safe return to the normal position during any power interruption
